Resection-reconstruction arthroplasty for giant cell tumor of distal radius

Management of Giant Cell Tumor of Distal Radius-Does Curettage Work?

Giant cell tumor affecting distal radius has been considered more aggressive, as compared to its counterparts in other locations. While resection has been advocated as the treatment of choice with lower rates of recurrence, curettage has reportedly led to superior functional outcomes. This retrospective study aimed to evaluate the functional and oncological outcomes of patients managed for GCT distal radius by either extended intralesional curettage (EIC) or resection and arthrodesis with radialisation of ulna (RRU), with respect to rates of local recurrence and function. Twenty-four patients operated for giant cell tumor of distal radius by a single surgeon from 2011 to 2021, were included in the study. The demographic, clinico-radiological, and surgical details were recorded and analyzed, as were the functional and oncological outcomes. At a median (IQR) follow-up of 6.3 years (range 2 years to 15.9 years), the rate of recurrence in curettage was found to be higher than that in resection but was not statistically significant (35.7% vs 20%, p > 0.05). Patients managed elsewhere and then presented to us for recurrence had a higher rate of local recurrence (66.6%, p = 0.01). Average time to recurrence was 14 months (range 2-24 months). On final follow-up, patients in curettage group had better functional outcomes in terms of grip strength and range of motion. Mean Modified Mayo Wrist score and MSTS score were 78.2 and 25.63, respectively, for EIC group and 69.6 and 25.75, respectively, for RRU group. Extended intralesional curettage resulted in an earlier rehabilitation with a mobile wrist and acceptable disease control when compared with resection and arthrodesis with radialisation of ulna.

Functional Outcomes of Centralization of the Ulna as a Method of Reconstruction Following Resection of Campanacci Grade 3 Giant Cell Tumor of the Distal Radius

PURPOSE

Wrist reconstruction after distal radial tumor resection poses a challenge to the orthopedic oncologist. We evaluated the functional outcomes of centralization of the ulna with ulnocarpal arthrodesis as a method of reconstruction following resection of distal radius tumors, using impairment measures and patient-reported outcomes.

METHODS

Evaluation of functional outcome was performed using the Musculoskeletal Tumor Society 93 scoring system and Disabilities of the Arm, Shoulder, and Hand questionnaire. We also determined hand grip strength on the affected side, time to radiologic union at the ulnocarpal junction and reduction in wrist circumference. Local complications and oncologic outcomes were recorded.

RESULTS

The study included 26 patients with Campanacci grade 3 giant cell tumor of the distal radius. Mean follow-up period in the study was 32.8 ± 12 months. Mean resection length was 10.3 ± 2.5 cm. Radiologic union at the ulnocarpal junction was achieved in 38.5%, 77% and 96% of the patients by 4, 5, and 6 months respectively. Mean hand grip strength was 74 ± 3.9% of the contralateral side whereas mean reduction in wrist circumference was 16.9 ± 6.4%. A good functional outcome with a mean the Musculoskeletal Tumor Society 93 score of 26 ± 1.4 and mean Disabilities of the Arm, Shoulder, and Hand score of 10.5 ± 6.3 was observed. Fracture of the ulna, hardware loosening, and reflex sympathetic dystrophy were each noted in 1 patient, with an overall complication rate of 10.7% (3/28). No patient had nonunion, infection, or local recurrence.

CONCLUSIONS

This is a simple and effective modality of reconstruction after resection of distal radial tumors. It provides good functional outcome and preservation of good hand grip strength, with low complication rates.

Reconstruction After En Bloc Resection of a Distal Radius Tumor. An Updated and Concise Review

The distal radius is rarely affected by either primary or metastatic bone cancers. The most frequent tumors of the distal radius are giant cell tumors, which are benign tumors with the propensity to invade. En bloc excision of giant cell tumors of the distal radius achieves a low recurrence rate but compromises the wrist joint, necessitates a significant reconstruction, and has functional consequences. Reconstruction after en bloc resection of a distal radius bone tumor is challenging. Furthermore, orthopedic oncologists disagree on treating such long bone anomalies most effectively. The present article summarizes the various biological and non-biological reconstruction techniques performed after en bloc resection of a distal radius tumor, discusses the advantages and disadvantages of each reconstruction strategy, and summarizes several case studies and case reports.

Wide resection for giant-cell tumor of the distal radius: which reconstruction? A systematic review of the literature and pooled analysis of 176 cases

Giant-cell tumor (GCT) is often more aggressive when located in the distal radius, and wide resection is then the gold-standard. No single reconstruction protocol is recommended, and the technique depends upon the surgeon's preferences. The aim of the present review was to determine the recurrence rate of GTC of the distal radius after intralesional treatment, to assess the results, advantages and complications of the various surgical techniques, and to draw up a decision-tree for surgical indications. The review of literature was performed in the main healthcare databases, searching for studies that reported results of wide resection and reconstruction of distal radius GCT. Local recurrence rates, metastasis rates, reconstruction techniques and respective results and complications were evaluated and analyzed. Sixteen studies were selected, for a total population of 226 patients; 6.0% and 0.9% experienced local recurrence and lung metastasis, respectively. Arthroplasty with non-vascularized or vascularized ipsilateral fibula were the most common techniques and were associated with the highest satisfaction rates: 86.4% and 88.0%, respectively. Arthroplasty with allograft presented a MusculoSkeletal Tumor Society (MSTS) score of 79.2% and arthroplasty with custom-made prosthesis presented an MSTS score of 81.8%. Arthrodesis was performed in 46 cases, with an MSTS score of 82.7%. Arthroplasty techniques are the most common in literature; they are used in patients who wish to conserve joint motion. Reconstruction with non-vascularized fibula seems to provide the best results, with lower morbidity. Arthrodesis is usually reserved for heavy manual workers or in case of arthroplasty failure.

Campanacci Grade III Giant Cell Tumors of Distal End Radius Treated With Wide Excision and Reconstruction: A Retrospective Case Series

Introduction

Campanacci Grade III Giant Cell tumors of the distal radius are difficult to manage as they are associated with a high recurrence rate. Wide excision of the distal radius and reconstruction with an ipsilateral proximal fibula or ulnar translocation reduces the recurrence rate significantly and gives acceptable function to the hand and wrist.

Methods and materials

This was a retrospective study of eight patients with Campanacci grade III giant cell tumors of distal radius treated with wide excision of distal radius followed by reconstruction at our institute. Four cases were operated on with ulnar translocation and four cases were operated on with ipsilateral proximal fibula grafting after wide excision of the distal radius. Patients were studied for the Musculoskeletal Tumor Society (MSTS) score and visual analogue scale (VAS) score for pain at one year, recurrence, and complications.

Results

The mean MSTS score of the total series was 24.75 ± 1.6. The mean VAS score for the total series was 1.62 ± 0.4. Of the eight cases, two cases had a recurrence, one patient had persistent wrist paint, and two patients had wrist subluxation.

Conclusion

Wide excision of the distal radius followed by reconstruction with a proximal fibula or ulnar translocation is a good option to avoid repeated surgeries in patients with Campanacci grade III giant cell tumors of the distal radius and achieve acceptable functional results for the wrist and hand.

Surgical challenges, novel techniques, and systemic treatment of giant cell tumour of bone of the distal radius

Aims

Giant cell tumour of bone (GCTB) treatment changed since the introduction of denosumab from purely surgical towards a multidisciplinary approach, with recent concerns of higher recurrence rates after denosumab. We evaluated oncological, surgical, and functional outcomes for distal radius GCTB, with a critically appraised systematic literature review.

Methods

We included 76 patients with distal radius GCTB in three sarcoma centres (1990 to 2019). Median follow-up was 8.8 years (2 to 23). Seven patients underwent curettage, 38 curettage with adjuvants, and 31 resection; 20 had denosumab.

Results

Recurrence rate was 71% (5/7) after curettage, 32% (12/38) after curettage with adjuvants, and 6% (2/31) after resection. Median time to recurrence was 17 months (4 to 77). Recurrences were treated with curettage with adjuvants (11), resection (six), or curettage (two). Overall, 84% (38/45) was cured after one to thee intralesional procedures. Seven patients had 12 months neoadjuvant denosumab (5 to 15) and sixmonths adjuvant denosumab; two recurred (29%). Twelve patients had six months neoadjuvant denosumab (4 to 10); five recurred (42%). Two had pulmonary metastases (2.6%), both stable after denosumab. Complication rate was 18% (14/76, with 11 requiring surgery). At follow-up, median MusculoSkeletal Tumour Society score was 28 (18 to 30), median Short Form-36 Health Survey was 86 (41 to 95), and median Disability of Arm, Shoulder, and Hand was 7.8 (0 to 58).

Conclusion

Distal radius GCTB treatment might deviate from general GCTB treatment because of complexity of wrist anatomy and function. Novel insights on surgical treatment are presented in this multicentre study and systematic review. Intralesional surgery resulted in high recurrence-rate for distal radius GCTB, also with additional denosumab. The large majority of patients however, were cured after repeated curettage.

Additive manufactured polyether-ether-ketone implants for orthopaedic applications: a narrative review

Polyether-ether-ketone (PEEK) is believed to be the next-generation biomedical material for orthopaedic implants that may replace metal materials because of its good biocompatibility, appropriate mechanical properties and radiolucency. Currently, some PEEK implants have been used successfully for many years. However, there is no customised PEEK orthopaedic implant made by additive manufacturing licensed for the market, although clinical trials have been increasingly reported. In this review article, design criteria, including geometric matching, functional restoration, strength safety, early fixation, long-term stability and manufacturing capability, are summarised, focusing on the clinical requirements. An integrated framework of design and manufacturing processes to create customised PEEK implants is presented, and several typical clinical applications such as cranioplasty patches, rib prostheses, mandibular prostheses, scapula prostheses and femoral prostheses are described. The main technical challenge faced by PEEK orthopaedic implants lies in the poor bonding with bone and soft tissue due to its biological inertness, which may be solved by adding bioactive fillers and manufacturing porous architecture. The lack of technical standards is also one of the major factors preventing additive-manufactured customised PEEK orthopaedic implants from clinical translation, and it is good to see that the abundance of standards in the field of additive-manufactured medical devices is helping them enter the clinical market.

Management of giant cell tumors of the distal radius: a systematic review and meta-analysis

PURPOSE

The treatment of giant cell tumors (GCT) of the distal radius remains challenging, with no consensus on the optimal surgical management. Surgical management remains the mainstay of treatment with options including intralesional curettage and en-bloc resection with reconstruction. The objective of this systematic review and meta-analysis was to evaluate and compare the outcomes of these two procedures.

METHODS

Using OVID-Medline and Embase databases, a systematic literature search was performed. Comparative studies, assessing intralesional curettage and en-bloc resection in patients with GCTs of the distal radius, were included. Data regarding rates of local recurrence, metastasis, overall complications, and functional outcomes, were collected and analyzed. The ROBINS-I tool was utilized for risk of bias appraisal within each study outcome.

RESULTS

Thirteen studies (n = 373 patients) reporting on 191 intralesional curettage procedures and 182 en-bloc resections were included in the analysis. The average age of participants was 31.9 (SD ± 2.4) years and average follow-up was 7.1 (SD ± 3.6) years. Patients that underwent intralesional curettage were more likely to develop local recurrence (Risk Ratio (RR) 3.3, 95% CI, [2.1, 5.4], p < 0.00001) when compared to patients that underwent en-bloc resection. In Campanacci grade 3 lesions, the risk for local recurrence was 5.9 (95% CI, [2.2, 16.3], p = 0.0006) times higher in patients that received intralesional curettage. Patients that underwent intralesional curettage showed an 84% reduction in the relative risk of developing overall complications compared to en-bloc resection (95% CI, [0.1, 0.4], p < 0.00001), and a larger decrease in Visual Analog Scale and lower Disabilities of the Arm, Shoulder, and Hand (DASH) scores (p < 0.00001). Risk ratio for developing a local recurrence, with PMMA versus bone graft following an intralesional procedure was not significant (RR 1.2, 95% CI, [0.6, 2.6], p = 0.62).

CONCLUSIONS

In the surgical management of GCT of the distal radius, intralesional curettage increased local recurrence compared to en-bloc resection with reconstruction, particularly in grade 3 tumors. However, it led to significantly fewer operative complications, lower pain scores, and improved functional outcomes compared to en-bloc resection. Both treatment options remain relevant in the contemporary management of GCTs of the distal radius. Surgical decision making should include both patient and tumor factors when determining the optimal treatment strategy for these patients. LEVEL 3 EVIDENCE: Meta-analysis of Level 3 studies.

Functional outcome following excision of giant cell tumour of the distal radius and reconstruction by autologous non-vascularized osteoarticular fibula graft

PURPOSE

Giant cell tumour (GCT) of the bone is a benign but locally aggressive tumour, commonly occurs at the metaphyseal-epiphyseal junction of the distal femur, proximal tibia, and distal radius. For Campanacci grade II and III lesions of the distal radius and in cases of recurrence, we usually carry out wide resection and reconstruction. There are numerous publications on the treatment of GCT of the distal radius. Still, reports on the functional outcome using non-vascularized fibular graft arthroplasty without fusion remain limited.

METHOD

We reviewed patients who underwent wide resection and non-vascularized fibular graft arthroplasty from 2007 to May 2014. The assessment was done with Musculoskeletal Tumour Society Score (MSTS), Toronto Extremities Scoring System (TESS) and Disability of the Arm, Shoulder and Hand (DASH) scores. We also reviewed the radiographic results.

RESULTS

Fifteen patients were recruited, of whom 10 cases used ipsilateral fibular graft and five used contralateral non-vascularized fibular graft. The average duration of follow up was 6 years (3.25-9.92 years). The average grip strength was 48.1% compared to the non-operated hand. The average MSTS score was 78.4 %, TESS score was 84%, and DASH score was 25.2. The average time to radiological union was 12.5 weeks. 64% (29-78%) of the range of movement is preserved compared to the normal side. The complication rate was 20%.

CONCLUSION

Fibula autograft arthroplasty is a feasible method of reconstruction after distal radius resection with good functional outcomes.

Giant Cell Tumor of the Distal Radius: Wide Resection, Ulna Translocation With Wrist Arthrodesis

Giant cell tumor (GCT) of the bone is a locally aggressive neoplasm and usually managed with extended curettage and adjuvant therapy, which is associated with reduced risk of recurrence. The juxta-articular distal radius giant cell tumor is challenging due to the destruction of subchondral bone and articular cartilage, making it difficult to salvage the wrist joint anatomy and function. Various methods described include wide resection and reconstruction of allograft or centralization of the ulna with wrist arthrodesis. We present the functional outcome of distal end radius GCT, which was successfully managed with wide local excision, ulna translocation, and wrist arthrodesis. At the two years follow-up, the patient shows excellent functional outcome with supination and pronation movements and no local recurrence.

Wrist Reconstruction after En bloc Resection of Bone Tumors of the Distal Radius

Wrist reconstruction after en bloc resection of bone tumors of the distal radius has been a great challenge. Although many techniques have been used for the reconstruction of long bone defects following en bloc resection of the distal radius, the optimal reconstruction method remains controversial. This is the first review to systematically describe various reconstruction techniques. We not only discuss the indications, functional outcomes, and complications of these reconstruction techniques but also review the technical refinement strategies for improving the stability of the wrist joint.

En bloc resection should be performed for Campanacci grade III giant cell tumors (GCT) as well as malignant tumors of the distal radius. However, wrist reconstruction after en bloc resection of the distal radius represents a great challenge. Although several surgical techniques, either achieving a stable wrist by arthrodesis or reconstructing a flexible wrist by arthroplasty, have been reported, the optimal reconstruction procedure remains controversial. The purpose of this review was to investigate which reconstruction methods might be the best option by analyzing the indications, techniques, limitations, and problems of different reconstruction methods. With the advancement of imaging, surgical techniques and materials, some reconstruction techniques have been further refined. Each of the techniques discussed in this review has its advantages and disadvantages. Wrist arthrodesis seems to be preferred over wrist arthroplasty in terms of grip strength and long‐term complications, while wrist arthroplasty seems to be superior to wrist arthrodesis in terms of wrist motion. All things considered, wrist arthroplasty with a vascularized fibular head autograft might be a good option because of better wrist function, acceptable grip strength, and a relatively lower complication rate. Moreover, wrist arthrodesis is still an option if the fibular head autograft reconstruction fails. Orthopaedic oncologists should familiarize themselves with the characteristics of each technique to select the most appropriate reconstruction method depending on each patient's situation.

Functional outcome in giant cell tumor of distal radius treated with excision and fibular arthroplasty: a case series

INTRODUCTION

Giant cell tumor (GCT) of bone is a locally aggressive benign neoplasm that is associated with a wide spectrum of biological activity ranging from latent benign to highly recurrent and has occasional metastatic potential. It affects the meta-epiphyseal region of long bones of young adults with most common site involved is the distal femur, followed by the distal radius. Plain radiographs and contrast-enhanced magnetic resonance imaging are the imaging modalities widely used followed by definite histopathology for diagnosis. Surgical treatment with curettage is considered optimal for local tumor control. Tumor excision with tumor-free margins is associated with lesser recurrence rates; however, for periarticular lesions this is usually accompanied with a suboptimal functional outcome.

METHODS

Eleven eligible patients (all females, mean age 39.2 years) with Campanacci grade III GCT of the distal radius who were treated by en bloc resection and reconstruction with non-vascularized proximal fibular autografts at a single centre between July 2016 and December 2017 were included in the study. The patients had a clinical and radiographic review every month for the first 6 months, then biannually for minimum of 2 years. The functional, oncologic and radiological outcomes of the patients were analyzed and recorded.

RESULTS

The mean duration of follow-up was 31.9 months. Bony union was achieved in all cases. The mean VAS score at 6 months was 1.1 (range 0-2). The mean Mayo Wrist score was 66.36 (range 55-80) with mean MSTS score was 21.09 (range 18-24). The average range of motion of the wrist was: 37.3° ± 6.9° of flexion, 47.1° ± 7.5° of extension, 57.3° ± 7.8° of supination and 63.6° ± 6.4° of pronation. The average graft length used was 15.6 cm. The complications noted were lung metastases which developed preoperatively, local site recurrence, wrist joint subluxation, foot drop and wound complication.

DISCUSSION AND CONCLUSIONS

The primary aim of treating GCT distal radius is oncologically sound resection with good functional outcome and cosmesis being secondary. Reconstruction with a non-vascularized proximal fibular autograft is a reasonable option after en bloc resection of the distal radius for giant cell tumor of bone having comparable results with other treatment modalities.

The reconstruction after en-bloc resection of giant cell tumors at the distal radius: A systematic review and meta-analysis of the ulnar transposition reconstruction technique

BACKGROUND

En-bloc resection of giant cell tumors (GCTs) of the distal radius remains the mainstay treatment for those with high-graded lesions. Several techniques have been described for reconstruction of the resected segment, of which transposition of the ipsilateral ulna is scarcely reported.

OBJECTIVES

To investigate the efficacy and safety of the different techniques of ulnar translocation following GCTs total resection.

METHODS

A systematic review and meta-analysis was conducted concerning the reported functional outcomes, including grip strength, range of forearm motion, functional scores, and new bone formation, as well as postoperative complications, such as delayed union, local recurrence and metastasis. The ranges of functional outcomes were reviewed and the pooled prevalence rates of complication and their respective 95% confidence intervals (95% CIs) were computed.

RESULTS

In a total of 12 studies, 90 patients (51.1% males, 84.8% had Campanacci grade III tumors) underwent five different reconstruction techniques. As compared to the normal side, the mean grip strength in the affected side ranged between 59 and 71%. The average union time was 1-8 months, while delayed union was reported in 50% (95% CI, 15.35 to 84.65) of patients whom their grafts were fixed with Steinmann pins. The shortest union time, the highest forearm supination and pronation degrees, new bone formation at the ulnar stump, and the highest functional scores were reported following a modified distal radius plate technique. Using a dynamic compression plate and a clover leaf plate provided lower, but considerable, functional outcomes.

CONCLUSION

Ulnar translocation following GCT en-bloc resection warrants additional investigation in large cohorts and well-designed studies to corroborate the promising outcomes presented in this review.

Outcomes of short segment distal radius resections and wrist fusion with iliac crest bone grafting for giant cell tumor

BACKGROUND

Distal radius is third most common site for occurrence of Giant cell tumor (GCT) of bone. Most of Campanacci grade II & III cases require resection. Reconstructions of these defect are challenging. Though fibular arthroplasty provides mobility at wrist but is fraught with complications of donor site morbidity and instability with wrist pain. Wrist arthrodesis with ulna translocation provides stable reconstruction but is cosmetically less appealing. We present a series of 12 cases of GCT of distal radius treated with short segment (6 cm or less) resections and wrist fusion with iliac crest grafting. We evaluated donor site morbidity, functional and oncological outcomes.

OBJECTIVES

To assess time to union, donor site morbidity, functional and oncological outcomes after wrist fusion with iliac crest bone grafting for distal radius resection (≤6 cm).

METHODS

Retrospective analysis was performed from a prospectively maintained database between January 2011 and December 2017, 12 patients (7 male and 5 female; 9 primary and 3 recurrent; all Campanacci grade III) were included. Mean age was 29 years (15-41 years) with mean resection length of 5.1 cm (4.5-6 cm). The dominant hand was involved in 6 patients. Time to union, donor site morbidity, functional and oncologiacal outcomes were evaluated. Functional outcomes were evaluated using Musculo-Skeletal Tumor Society (MSTS) score and Patient Rated Wrist Evaluation (PRWE) score. Grip strength and arc of forearm rotation were also evaluated.

RESULTS

All patients were available for analysis. No symptomatic donor site morbidity was observed. One patient had prominent implant following a fall and delayed union. Mean time to union for 22 osteotomy sites in rest of 11 patients (both proximal and distal) was 6 months (4-11 months). At median follow up of 45 months (18-78 months) 2 patients had soft tissue recurrence, 1 had a stable pulmonary metastasis. Local Recurrence rate was 17%. All patients returned to their pre surgery activity. Mean MSTS score was 25 (19-29) and PRWE score was 12 (6-28). Grip strength and Prono - supination measurements were available in 10 patients. Grip strength was 69% of non operated limb. Mean supination was 53° (0° to 80°) and mean protonation was 73° (40° to 80°). Mean arc of rotation was 126° (80° to 160°).

CONCLUSION

Reconstruction of distal radius bone defects with Iliac crest bone grafting and wrist arthrodesis retains prono-supination while maintaining wrist girth (cosmesis). The oncologic and functional outcomes make it an acceptable modality in selected cases of distal radius tumours with short resection length (≤6 cm).

Hernia mesh prevent dislocation after wide excision and reconstruction of giant cell tumor distal radius

Giant cell tumor (GCT) remains as major health problem. GCT which located at the lower end of the radius tends to be more aggressive. Wide excision and reconstruction of the wrist in stage 3 of distal radius GCT lesion is an optimal modality to prevent tumor recurrence. However, dislocation often occurs as its complication. We are reporting patient with GCT of distal radius treated with wide excision and reconstruction using nonvascularized fibular graft and the addition of hernia mesh. Circumferential non-absorbable polypropylene hernia mesh was applied, covered radioulnar joint and volar aspect of radius, and served as additional support to prevent dislocation. During five years and two months of follow-up, we found no dislocation in our patient. Furthermore, good functional outcome was obtained. Our finding suggests that the addition of hernia mesh after wide excision and reconstruction with nonvascularized fibular graft may benefit to prevent dislocation and provides an excellent functional outcome.

Epidemiological and Clinical Features of Primary Giant Cell Tumors of the Distal Radium: A Multicenter Retrospective Study in China

Giant cell tumors of the distal radius are challenging for surgeons because they are associated with high recurrence rates and poor functional outcomes. Between June 2005 and October 2015, patients with primary giant cell tumors of the distal radius were recruited from seven orthopedic centers in China. The patients’ clinical features and demographic characteristics were obtained from medical records and reviewed retrospectively. Overall, 48 cases of giant cell tumors of the distal radius were assessed in this study. These patients were more likely to be between 20 and 40 years of age, to have a Campanacci grade of III, and to undergo a surgical style of resection. The prevalence of pathological fractures was 12.5% overall (20.0% in men and 4.3% in women). The prevalence of local recurrence was 30.0% overall (38.1% in men and 21.1% in women) during the average follow-up period of 62.5 months, with a pulmonary metastasis rate of 5.0%. Giant cell tumors of the distal radius were predominant in men and were more likely to recur locally than around the knee. These findings suggest that it is crucial to evaluate the optimal surgical approach for balancing local recurrence control and functional outcomes to reduce the disease burden.

Functional outcome of en bloc resection of a giant cell tumour of the distal radius and arthrodesis of the wrist and distal ulna using an ipsilateral double barrel segmental ulna bone graft combined with a modified Sauve-Kapandji procedure

Giant cell tumour of the distal radius is a locally aggressive lesion. In this study, we performed a wrist arthrodesis reconstruction with an ipsilateral double barrel segmental ulnar bone graft combined with a modified Sauve-Kapandji procedure for a giant cell tumour of the distal radius. From January 2007 to September 2013, we followed eight patients for a mean duration of 36 months. One patient developed a recurrence and was treated by amputation; the other seven patients achieved radiological union in about 8 months. There was no wrist instability, deformation or dislocation; the mean range of motion of the forearm achieved 75° of supination and 70° of pronation. The patients could recover reasonable grip strength. This new operative procedure can excise the tumour with a low rate of recurrence, fewer functional deficits and fewer complications than reported for other procedures.

Clinical and Radiographic Results of Reconstruction with Fibular Autograft for Distal Radius Giant Cell Tumor

OBJECTIVE

To evaluate the result of en bloc resection and reconstruction of the distal radius with a non-vascularized fibular autograft for giant cell tumor (GCT) of bone.

METHODS

Between 2005 and 2015, 12 eligible patients (seven males, five females, mean age 31.3 years) with grade III GCT of the distal radius were treated by en bloc resection and reconstruction with non-vascularized proximal fibular autografts in four Chinese institutions (members of Giant Cell Tumor Team of China). The patients had a clinical and radiographic review every 6 months for the first 2 years then annually thereafter. The functional, oncologic and radiological outcomes of the patients were analyzed.

RESULTS

The mean duration of follow-up was 39.6 months. Bony union was achieved in all cases. None of the patients were dissatisfied with the shape and appearance of the wrist. The mean MSTS score was 25.23 ± 2.38 (range, 22-29). The mean DASH score was 13.0 (range, 6.7-33.3). The average range of motion of the wrist was: 35.8° ± 14.5° of extension, 14.0° ± 8.4° of flexion, 15.5° ± 6.7° of radial deviation, 19.4° ± 10.1° of ulnar deviation, 57.2° ±18.9° of pronation and 44.0° ± 24.8° of supination. The average percentage of grip strength was 55.2% ± 29.0% compared with that of the contralateral side. One localized soft tissue recurrence occurred; it was successfully managed by excision. Lung metastases developed postoperatively in one case and were treated by gamma knife radiotherapy. There was radiographic evidence of radiocarpal arthritis in eleven patients, bone resorption in ten, distal radioulnar joint diastasis in six, ulnar deviation of the wrist in seven, subluxation of the carpal bone in three and dislocation of the carpal bone in one patient.

CONCLUSIONS

Reconstruction with a non-vascularized proximal fibular autograft is a reasonable option after en bloc resection of the distal radius for giant cell tumor of bone.

What are the Functional Results, Complications, and Outcomes of Using a Custom Unipolar Wrist Hemiarthroplasty for Treatment of Grade III Giant Cell Tumors of the Distal Radius?

PURPOSE

A giant cell tumor (GCT) of bone presenting in the distal radius is rare, however, when they occur, Campanacci Grade III tumors can present formidable reconstructive challenges. They are associated with a high local recurrence rate with intralesional treatment, therefore approaches to reconstruct the wrist after en bloc resection warrant study.

QUESTIONS

We asked: (1) What are the functional outcomes after en bloc resection and reconstruction of the wrist with a unipolar prosthesis in patients with Grade III GCT of the distal radius? (2) What complications occur with use of a unipolar prosthesis in these patients? (3) What are the oncologic outcomes with using en bloc resection and reconstruction with a custom unipolar wrist hemiarthroplasty for Grade III GCTs of the distal radius?

METHODS

We retrospectively analyzed 10 patients with Campanacci Grade III GCTs of the distal radius treated by a unipolar prosthesis after wide resection of the tumor between January 2008 and October 2013. During that period, all patients at our medical group who presented with a Grade III GCT of the distal radius were treated with wide resection and reconstruction using a custom unipolar implant. Pre- and postoperative pain at rest were assessed according to a 10-cm VAS score. The functional outcomes of the wrist were assessed using the modified Mayo wrist score, and the degenerative changes were evaluated radiographically by a new rating system based on the Knirk and Jupiter scale. We also analyzed tumor recurrence, metastases, and complications associated with the reconstruction procedure. All patients were available for followup at a mean of 52 months (range, 24-90 months).

RESULTS

Although the complication rate associated with prosthetic arthroplasty was relatively high (six of 10), none of our patients experienced severe complications. Two patients reported having occasional pain of the involved wrist at the time of final followup (VAS, preoperative versus postoperative: 0 versus 3; 5 versus 2, respectively). The mean modified Mayo wrist score was 68 (range, 45-90). Degenerative changes were found in three wrists (Grade 1, two patients; Grade 2, one patient). Aseptic loosening occurred in one patient and wrist subluxation occurred in two patients. Lung metastases or local tumor recurrence were not observed.

CONCLUSIONS

Because of the proportion of patients who had complications and progressive degeneration with this approach, we recommend first exploring alternatives to reconstruction with custom unipolar wrist hemiarthroplasty after resection of Grade III GCTs of the distal radius, such as fibular autografting. However, this technique provides an alternative for patients with concerns regarding possible morbidity associated with autografting, and for situations when allograft is not available.

Topographic matching of distal radius and proximal fibula articular surface for distal radius osteoarticular reconstruction

During osteoarticular reconstruction of the distal radius with the proximal fibula, congruity between the two articular surfaces is an important factor in determining the quality of the outcome. In this study, a three-dimensional model and a coordinate transformation algorithm were developed on computed tomography scanning. Articular surface matching was performed and parameters for the optimal position were determined quantitatively. The mean radii of best-fit spheres of the articular surfaces of the distal radius and proximal fibula were compared quantitatively. The radial inclination and volar tilt following reconstruction by an ipsilateral fibula graft, rather than the contralateral, best resembles the values of the native distal radius. Additionally, the ipsilateral fibula graft reconstructed a larger proportion of the distal radius articular surface than did the contralateral. The ipsilateral proximal fibula graft provides a better match for the reconstruction of the distal radius articular surface than the contralateral, and the optimal position for graft placement is quantitatively determined.

Carpus translocation into the ipsilateral ulna for distal radius recurrence giant cell tumour: A case report and literature review

Giant cell tumour is a frequent benign neoplasm. It is characterized by local aggressive behaviour and frequent recurrence. The most common localization is the distal femur followed by proximal tibia (40%). The distal radius is the next place (10%). The recurrence in the distal radius in primary cases is reported 10%, in recurrent cases is almost 30% and depends to the kind and the stage of the tumour at the time of treatment. Multiple options have been reported for treatment of Campanacci III giant-cell tumour (GCT) of the distal radius after resection. Actually the treatment of recurrence remains a real dilemma. Several reconstructive options (e.g. resection arthroplasty, prosthetic replacement, arthrodesis, ulnar translocation, centralization of the carpus over the remaining ulna, use of vascularized or nonvascularized fibular graft, with or without, arthrodesis, have been described up to date. We present a case of recurrence of GCT of distal radius after curettage, where we selected the centralization of the ulna into the carpus as a salvage procedure with satisfactory results. The procedure provides a valid option for the management of recurrent GCTs of distal radius offering excellent cosmetic and acceptable functional result.

Reconstruction of the distal radius with non-vascularised fibular graft after resection of giant cell tumour of bone

PURPOSE

To evaluate outcomes of wide resection and reconstruction of the distal radius with non-vascularised autogenous fibular grafts for giant cell tumour (GCT) of bone.

METHODS

Medical records of 7 men and 5 women aged 22 to 47 (mean, 31) years who underwent wide resection of the distal radius and reconstruction with non-vascularised autogenous fibular grafts for GCT of bone were reviewed. The mean length of the resected radius was 9 (range, 7-11) cm. The ipsilateral proximal fibula with a small portion of attached ligament was harvested. The articular surface of the graft was fixed to the scapholunate articular surface by Kirschner wires, and the ligament of the fibular head was sutured to the carpal ligaments. The graft was fixed to the proximal radius with a small dynamic compression plate. Iliac cancellous bone graft was added. Pain, instability, and functional status were assessed. Wrist joint movements were measured using a goniometer. The grip strength was measured. The operated and contralateral sides were compared.

RESULTS

The mean follow-up was 24 (range, 20-27) months. All patients achieved radiological union after a mean of 16 (range, 14-20) weeks. The mean active range of movement in the operated wrists was 32º dorsiflexion, 38º palmar flexion, 15º radial deviations, 12º ulnar deviations, 50º supination, and 60º pronation. Compared with the contralateral wrists, the operated wrists regained 60% of the function, with satisfactory grip strength, and normal finger and thumb movements and hand sensation. No patient had recurrence after 2 years. Two patients had minor dorsal subluxation, which was resolved with a wrist brace. Three patients had superficial infection, which was resolved with intravenous antibiotics and dressings. Two patients had peroneal nerve palsy, which recovered completely in 12 weeks.

CONCLUSION

Non-vascularised fibular grafts for reconstruction of the distal radius after resection of a GCT of bone achieved good cosmetic and functional outcomes.

Partial wrist arthrodesis versus arthroplasty for distal radius giant cell tumours

PURPOSE

The purpose of this study was to evaluate the clinical efficacy of using the proximal fibular graft for partial wrist arthrodesis or arthroplasty after the resection of giant cell tumours of the distal radius.

METHODS

Between February 2006 and August 2010, 14 patients (seven males, seven females; average age, 35.7 years) with grade II and III giant cell tumours of the distal radius were treated by tumour resection and autologous proximal fibular grafts to reconstruct the wrist in our hospital. Seven patients each were treated by wrist arthroplasty and partial wrist arthrodesis, and were followed up for 2.2-6.8 years (average, 3.9 years).

RESULTS

All patients achieved primary healing. No tumour recurrence was observed during follow-up in any of the patients. No statistically significant difference in forearm rotation was observed between patients undergoing the two different treatments. However, wrist flexion-extension activities were significantly better and the wrist grip strengths were significantly worse in the arthroplasty group than in the arthrodesis group. The Musculoskeletal Tumour Society score did not significantly differ between the groups.

CONCLUSIONS

Overall, joint arthroplasty remains a favourable treatment with regard to the functional outcome for giant cell tumours of the distal radius; however, some of these patients may have a weaker grip strength. In comparison, partial wrist fusion appears to provide a durable and stable wrist with good long-term functional outcome.

En bloc excision and autogenous fibular reconstruction for aggressive giant cell tumor of distal radius: a report of 12 cases and review of literature

INTRODUCTION

Giant cell tumor (GCT) of distal radius follows a comparatively aggressive behaviour. Wide excision is the management of choice, but this creates a defect at the distal end of radius. The preffered modalities for reconstruction of such a defect include vascularized/non-vascularized bone graft, osteoarticular allografts and custom-made prosthesis. We here present our experience with wide resection and non-vascularised autogenous fibula grafting for GCT of distal radius.

MATERIALS AND METHODS

Twelve patients with a mean age of 34.7 years (21-43 years) with Campanacci Grade II/III GCT of distal radius were managed with wide excision of tumor and reconstruction with ipsilateral nonvascularised fibula, fixed with small fragment plate to the remnant of the radius. Primary autogenous iliac crest grafting was done at the fibuloradial junction in all the patients.

RESULTS

Mean follow up period was 5.8 years (8.2-3.7 years). Average time for union at fibuloradial junction was 33 weeks (14-69 weeks). Mean grip strength of involved side was 71% (42-86%). The average range of movements were 52° forearm supination, 37° forearm pronation, 42° of wrist palmerflexion and 31° of wrist dorsiflexion with combined movements of 162°. Overall revised musculoskeletal tumor society (MSTS) score averaged 91.38% (76.67-93.33%) with five excellent, four good and three satisfactory results. There were no cases with graft related complications or deep infections, 3 cases with wrist subluxation, 2 cases with non union (which subsequently united with bone grafting) and 1 case of tumor recurrence.

CONCLUSION

Although complication rate is high, autogenous non-vascularised fibular autograft reconstruction of distal radius can be considered as a reasonable option after en bloc excision of Grade II/III GCT.
